An isotope emits an electron and an anti-neutrino during radioactive decay. The 11. electron moves east with a momentum of 9.28 x 1028 kg m/s and the anti-neutrino moves north with a momentum of 7.47 x 1027 kg m/s as shown in the diagram below. electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree. 3) Answer If scientists only knew where the electron and recoiling nucleus went, which conservation law would lead them to believe another particle must be involved? b.

    The carbon isotope 14C is used for carbon dating of archeological artifacts. 14C ( mass 2.34×10−26kg) decays by the process known as beta decay in which the nucleus emits an electron (the beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron ( mass 9.11×10−31kg ) has a speed of 5.7×107 m/s and the neutrino has a momentum of 6.9×10−24 kg⋅m/s ....
